    2014 5.7 270 Comp Cam w/phaser limiter, long tubes. Reduced throttle.

    Ive got 40 hours and an email tune in this hemi, before I ask here for help. Its not letting the the throttle blade open on my Snap on or OTC scan tools past about 12 % but on the follower test with engine off it works. In my Beta I stumbled on the Engine Diagnostic table with tourque settings and such and played with them some. Got it to scream to red line about 6 times then no more throttle plate past 12%. Restart the car and it resets and fine for a few revs, no matter the run time. Played with ETC controls too under Airflow. Please what am I missing on getting the TPS system dialed in?. Im guessing its a tourque setting but Ive maxed those out. I do know it short shifts like there is no TPS showing up in the tranny. I did not have time to do the mechanical work so he sent it off and got it done and then trailered it to me to tune, since I did the OEM tune a year or so ago. I do realize the tech could have bumped the Throttle Body, but I sure hated to order one when one of you guys could tell me while laughing what I am doing wrong. Hats off to you Dodge Tuners. I can see its a specialist type tune. Thanks in advance.

    I don't know if this will help, but here is my tune in-progress for a 2014 5.7 Charger Pursuit with a Comp stage 2 cam with Doug Thorley tri-y headers and some exhaust port work.mymod08-024.hpl

    Yes. I have about 30 tune files for this car, but this is a base I go to.
